JOHN EDWIN KILBUBN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR '10 HALE AND KILBUBN COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE.

CAR-SEAT.

Application filed August 11, 1911.

To all whom it may concern:

Be it known that I, JOHN EDWIN KIL- noun, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car-Seats, of which the following is a specification.

This invention relates to car-seats, and more particularly to seats of the type known as stationary cross seats for use in cars mounted transverse to the length of the car and not arranged for reversal of the facing direction.

The invention is directed to the provision of a seat of this type of a novel construction, such that the greatest possible amount of seating space is provided in a structure which is of the least possible weight.

A seat constructed in accordance with the invention comprises a pedestal, an arm secured thereon consisting of two integral port-ions, one extending substantially horizontally and the other extending upwardly, and seatand back-cushions mounted upon this arm. The arm is made of sheet-metal and is of a particular construction, whereby the desired results are obtained. By reason of the use of sheet-metal in making the arm,

the requisite strength may be obtained, without objectionably increasing the weight, and also without increasing the size of the arm to such extent as would obstruct the entrance to the next seat behind. Furthermore, in accordance with the invention, the maximum seating capacity is obtained by arranging the parts so that the seat-cushion extends beyond the arm at one end, the arm being so arranged that the upright portion thereof extends upwardly in rear of the seat cushion and adjacent to the rear edge thereof.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a seat constructed in accordance with the invention, Fig. 2 is a front view of the seat broken away in part, Fig. 3 is an elevation of the supporting arm as seen from the inner side thereof, and Figs. 4, 5 and 6 are sectional views on lines H, 5-5 and 66 respectively of Fig. 3.

Referring to these drawings, the pedestal Specification of Letters Patent.

Serial No. 643,535.

for supporting one end of the seat is shown at 1, and is preferably formed of a single piece of sheet-metal. pressed to the desired configuration. -As shown, the pedestal is of oval cross-section, flaring at its lower end and at its upper end provided with arms 2 extending forwardly and rearwardly. The seat-cushion is shown at 3 and the backcushion at 4-, and these two cushions are mounted upon the pedestal l by a single supporting'arm at each end of the seat. The construction. of this supporting arm is shown in detail in Figs. 3, l, 5 and 6. It consists of two integral portions 5 and (3, one extending substantially horizontally and the other extending upwardly. The arm is of channel-section throughout except at the junction of the two portions thereof, where it is made of boxsection by being reinforced so as to give it greater strength at this point. At the lower edge of thehorizontal portion 5, is an inwardly extending flange 7. A similar flange 8 is provided along the upper edge of the portion 5, this flange being inclined in the direction of its length so that the seat-cushion 3 supported thereon-will lie at the desired angle. Along the front edge of the portion 5 is a flange 9, which serves to give the structure a more attractive appearance. The arm is secured upon the pedestal 1 by means of bolts passing through openings in the flange 7 and engaging the ends of the arms 2 at the upper end of the pedestal. To permit of employing this means for securing the arm upon the pedestal, the flange 7 is braced so as to hold it rigidly with respect to the body of the portion 5 of the arm. For this purpose, braces 10 are provided, one on either side of each of the bolt-holes through the flange 7. Each of these braces is preferably a piece of sheet-metal curved transversely and placed at an incline between the flange 7 and the adjacent wall of the arm, the brace being so shaped that its edges abut against the flange 7 and the body of the arm throughout their entire length. The braces 10, so positioned, are secured rigidly to the arm, preferably by welding them thereto, and when so secured they hold the flange 7 rigidly with respect to the body of the arm and distribute the strains from the securing bolts over a large area of the arm. Fig. 2

shows the bolts 11 passing through openings in the flange 7 and engaging the arms 2 of the pedestal or clamps 12 secured thereto.

At the junction of the horizontal portion and the upright portion of the supporting arm, the latter is reinforced to give it greater strength, and this is preferably accomplished by employing an angular piece ,13

of sheet-metal cut to the shape of the angle substantial width.

I The arm is mounted upon the pedestal in ,the'ma'nner shown in Figs. 1 and 2, and the seat-cushion 8 is then positioned upon the horizontally disposed portion of the arm. For holding the seat-cushion, in position, a pin 15 is preferably provided upon the flange 8, this pin being received in a suitable opening formed in the frame of the cushion 3. As shown in Fig. 2, the seatcushion 3 is of such length that it extends beyond the supporting arm at either or both ends of the cushion, and the upright portion of the arm extends upwardly in rear of theseat-eushionand adjacent to the rear edge thereof. The upright portion 6 of the arm is then secured to the end edge of the back-cushion 4, with the flange 14 lying against the rear face of the cushion adj acent to the end edge thereof.

As thus constructed, the maximum seating capacity is obtained by extending the seat-cushion 3 beyond the supporting arm and having the arm extend about the rear edge of the cushion rather than about the end edge. The desired light weight of the structure is secured by forming the sup-' porting arm from sheet-metal, but the structure made as illustrated and above described is of the requisite strength, notwithstanding the use of sheet-metal in the supporting arm, and furthermore the arm does not extend backwardly from the rear edge of the seat-cushion so far as to encroach upon the knee room for occupants of the seat next behind. These desirable characteristics result from the use of an arm having the horizontal and upright portions thereof integral, of channel-section throughout, and reinforced at the junction of the two portions.

Having now described my invention,

what I claim as new therein and desire to secure by Letters Patent is as follows 1. A car-seat comprising the combination of a pedestal, an arm formed of sheet-metal and having two integral portions one extending substantially horizontally and the Other extending upwardly, said horizontal portion having a vertically-disposed bodyportion and integral flanges at the upper and lower edges thereof, means for securing said lower flange to the pedestal, means for bracing said lower flange with respect to the body-portion, a seat-eushion mounted on said upper flange with its rear edge adjacent to but in front of said upwardly extending portion of the arm, means for reinforcing said arm at the junction of the two portions thereof, and a back-cushion of less length than the seat-cushion having its end secured to said upwardly extending por tion of the arm, substantially as set forth.

2. A car-seat comprising the combination of a pedestal, an arm secured thereon having a substantially horizontal portion and an integral upwardly extending portion, and seatand back-cushions secured upon said arm, said arm being formed of sheetmetal and having a vertically-disposed body portion throughout, integral flanges at the upper and lower edges of the horizontal portion, an integral flange at the rear edge of said upwardly extending portion, and means for reinforcing said arm at the junction of the two said portions thereof, said means consisting of a piece of sheet-metal united at its edges to the piece forming the arm, substantially as set forth.

In a ear-seat, a cushion-supporting member formed of sheet-metal and comprising a horizontally-disposed portion and a back-supporting arm formed integral therewith and extending upwardly from one end thereof, said horizontally-disposed portion having an integral flange at its upper edge and said arm having an integral flange at its rear edge, a sheet-metal reinforce united to said member and making the same of box section at the angle therein, means for supporting said member, a seat-cushion mounted upon the flange on said horizontally disposed portion with its end extending beyond the same and said arm, and a back-cushion having its end secured to said arm and bearing against the flange thereon, substantially as set forth.

This specification signed and witnessed this 8th day of August, 1911.
